这里的错误确实相当神秘。我还必须做很多搜索来找到解决这个问题的方法。

但是一旦找到它，解决方案就相当简单。在服务器实例(部署了 dokku 的位置(中，执行以下两个命令：

dokku config:set --global CURL_TIMEOUT=1200
dokku config:set --global CURL_CONNECT_TIMEOUT=180

尝试下载构建包的 curl 命令没有足够的时间来执行。我们只是给他们一点额外的时间。这应该可以解决您的问题。

我最初在这里找到了这些命令：https://github.com/dokku/dokku/blob/master/docs/deployment/methods/buildpacks.md
